“…This considerable development in the ornamental use of H. macrophylla was made possible thanks to the great number of agronomic experiments carried out over the past 30 y. They have shown the influence of water restriction (Cameron et al, 2006;Morel, 2001), root volume restriction (Yeh and Chiang, 2001), temperatures (Adkins et al, 2003;Bailey and Weiler, 1984;Post, 1942;Vidalie, 1986), photoperiod (Guo et al, 1995;Morita et al, 1980;Shanks et al, 1986), light intensity (Bailey et al, 1987;Dugardin and Balemans, 1991;Rusch et al, 1986), plant growth regulators (Bailey et al, 1986;Joustra, 1989;Morita and Osuka, 1981) and relative air humidity (Codarin et al, 2006) on plant de- velopment. These experiments made it possible to capitalise on knowledge about existing interactions between plant development and certain environmental factors.…”

“…Many researchers have attempted to identify the climatic factors favorable to floral induction. Thus, temperatures below 18°C (Bailey and Weiler, 1984;Post, 1942) and a short photoperiod of less than 12 h (Guo et al, 1995;Morita et al, 1980;Shanks et al, 1986) are favorable to floral transformation. Despite some interesting results, this research has not yet made it possible to control floral transformation during production.…”

Hydrangea macrophylla is a horticultural plant of considerable commercial interest that has been widely studied with the aim to more effectively control the different stages of its development during production. However, although floral transformation is a key factor underlying the commercial quality of the product, it remains difficult to control despite these efforts. The floral transformation sequence consists of three successive phases: floral induction (B1), floral evocation (B2), and floral organogenesis (B3). The first is a phase of vegetative organogenesis without elongation leading to the formation of a bud composed of eight phytomer primordia under inductive climatic conditions. This work shows that climatic conditions favorable to floral transformation must be continuously applied without interruption throughout phase B1 to ensure the formation of the floral bud in Hydrangea macrophylla ‘Leuchtfeuer’. In the opposite case, floral transformation is stopped and vegetative growth begins once again.

“…Many studies have been conducted to determine the optimal conditions for the flower-bud initiation and development of H. macrophylla (Bailey and Weiler, 1984;Litlere and Stromme, 1975;Morita et al, 1980;Piringer and Stuart, 1958;Shanks and Link, 1951;Shanks et al, 1986). There have been several reports concerning the process by which inflorescences develop.…”

The composition and development of inflorescences were compared between a lacecap and hortensia Hydrangea macrophylla (Thunb.) Ser. In this study, we used 'Blue Sky' cuttings as lacecap plants and mutated branch cuttings as hortensia plants. The only difference between the inflorescences of lacecap and hortensia was the structure of the upper nodes near the terminal flowers. Partial inflorescences set on the upper nodes of the lacecap, whereas decorative flowers set on the upper nodes of the hortensia. The basic developmental process of the inflorescence was similar in both the lacecap and hortensia. Several pairs of axillary primordia were successively initiated on the inflorescence primordia that were followed by the initiation of terminal flowers. These terminal flowers developed as non-decorative flowers, whereas most axillary primordia developed into partial inflorescences. In hortensia, however, the axillary primordia at the upper nodes differentiated into decorative flowers, which indicates that the change in the inflorescence structure during the mutation from lacecap to hortensia is the replacement of partial inflorescences with decorative flowers on the upper nodes of the inflorescence axes.
